Q.1. Search for Information on Chandrayaan and
Mangalyaan discuss this achievement in the classroom
Ans: Information about Mangalyaan and Chandrayaan |
- Mangalyaan, (official name – Mars Orbiter Mission, English: ), is India's first Mars mission. This is India's first interplanetary mission. In fact, it is an ambitious space project of the Indian Space Research Organization. Under this project, a Mars orbiting satellite was successfully launched by Polar Satellite Launch Vehicle (PSLV) C-25 from the Satish Dhawan Space Center in Sriharikota, Andhra Pradesh on 5 November 2013 at 2:38 PM.
With this, India has now also joined the list of countries that have sent their spacecraft to Mars. Although several missions to Mars have failed so far, India became the first country in the world to succeed in its first attempt after reaching Mars on 24 September 2014 and became the fourth country in the world after Soviet Russia, NASA and the European Space Agency. It is also the cheapest mission sent to Mars. India became the first country in Asia to do so. Because earlier China and Japan had failed in their Mars missions.
In fact, it is a technology demonstration project aimed at developing the design, planning, management and execution of interplanetary space missions. The orbiter will continue to orbit Mars with its five instruments and collect data to achieve scientific objectives. The spacecraft is currently being monitored by the Indian Deep Space Network antenna from the ISRO Telemetry, Tracking and Command Network (ISTRAC), Spacecraft Control Center in Bangalore. The total cost of the Mangalyaan mission is 450 crores.
- Mangalyaan was launched from Sriharikota in the state of Andhra Pradesh towards Mars from the Satish Dhawan Space Center on November 5, 2013. PSLV C-25 missile was used for this purpose. The spacecraft remained in Earth orbit for approximately 25 days, and on November 5, 2013, the spacecraft exited Earth orbit towards Mars and entered Mars orbit on September 24, 2014.
Five experimental payloads of 15 kg each were sent in this mission.
- Methane sensor – The methane sensor that will be sent to Mars will weigh 3.59 kg. This sensor is capable of scanning the entire Mars within six minutes.
- Another instrument is the thermal infrared spectrometer. Its weight is four kilos. It will work to observe the surface of Mars.
- Mars Color Camera is another device weighing 1.4 kg.
- The Lamen Alpha Photometer weighs 1.5 kg. The instrument will be tasked with detecting molecular hydrogen in the Martian atmosphere
Chandrayaan
- Chandrayaan 1 is the Indian Space Research Organization's
(ISRO) spacecraft carrying the first stage of the lunar mission.
- Chandrayaan 1 is an unmanned spacecraft that consists of two parts, one for orbiting the moon and one for landing on the moon.
- Chandrayaan was launched from the Satish Dhawan Space Center in Sriharikota on 22 October 2008 by the Advanced Generation Polar Satellite Launch Vehicle (PSLV-C11) launch vehicle.
- The spacecraft was successfully launched into lunar orbit on November 8, 2008. On November 14, 2008, at 8:06 PM, the Moon Impact Probe attached to the spacecraft was successfully detached. After a journey of about 25 minutes, the probe hit the 'Shackleton Crater' near the south pole of the Moon.
- As the Indian flag is hoisted on all four sides of this cubic probe, symbolically the Indian flag has reached the moon and India has become the fourth country in the world to achieve this.
- The mass of this remote sensing spacecraft was 1130 kg at launch and 675 kg when it reached lunar orbit.
- The spacecraft carries telemetry instruments for high-resolution visual and infrared light as well as X-rays.
- The mission of this spacecraft is two years and during this period it is expected to survey the surface of the moon and create a complete chemical map of it as well as create a three-dimensional (3D) map of the lunar structure. The polar regions of the Moon are given more importance, as there is a possibility of ice.
- The total cost of this campaign is approximately Rs 386 crore.
- There were five payloads of ISRO and six payloads of other space agencies in this mission. These include NASA, ISA and the Bulgarian Space Agency. The equipment of these space agencies is being transported in non-dimensional form.

Q.2. What is GPS? What are its uses?
Ans:- What exactly is GPS? – What is GPS?
The full form of GPS is Global Positioning System. And
the GPS system is a satellite system that shows the direction of the whole
world, this GPS system provides the information and time of any place on earth
to the GPS receiver. And using this system we can travel on any roads on
earth. Pretty much any roads and the distance between those roads.
History of
GPS – The defense forces installed it
in 1960s for their border guards so that they could monitor and track enemy
locations, but the technology was opened up to everyone in the world in 1995
and the system was made available to everyone. So today we see this system
in everyone's mobile.
How does
GPS work? How does GPS work?
GPS is a network of 30 satellites located 20,000 kilometers
from our Earth's surface. And it moves around in the earth's
orbit. When we turn on the mobile GPS, 4 satellites check our location,
and periodically these four satellites transmit our location and time information
through signals, the speed of which is transmitted at the speed of
light. And your mobile works as a receiver at this time. So we get
the correct location information.
Uses of
GPS – Uses of GPS
GPS system basically helps us to know our location.
GPS system basically helps us to get correct time
information.
GPS system basically helps to move from one place to
another.
GPS system is used to track the location of a person.
Q.3 What is the importance of nuclear energy for
India? Collect information about one or two nuclear power plants in India

Collect information about cyber threats to national security. Find out the
various means used to fight cyber threats.
- Ans:-E-crime, or cyber-crime, whether related to theft, hacking or denial of service to essential systems, has become a fact of life. The threat of industrial cyber espionage, in which one company actively attacks another through cyberspace, to obtain high-value information.
- · Cyber terrorism presents challenges for the future. We must be prepared for terrorists seeking to take advantage of our growing Internet dependence to attack or disable key systems.
- · The CPNI works within the National Cyber Security Center (NCSC), the Cabinet Office and leads government departments and agencies to advance the UK's cyber security program to tackle these threats.
- · Cyber threats are a big deal. A cyber-attack can cause electrical blackouts, failure of military equipment, and breach of national security secrets. They can steal valuable, sensitive data like medical records. They can disrupt phone and computer networks or paralyze systems by making data unavailable.
- · Ways of Cyber Attack for National Security
- · Every country should adopt a cyber-security strategy that avoids costly and cumbersome regulatory approaches. Instead, they should include key elements that create a dynamic cyber security defense. The main components include:
- · Organizing strong international cyber security investments. If a country wants to take an active role in fighting espionage and cybercrime, a country needs a comprehensive set of policies. It must enhance and continue coordination and cooperation with its friends and allies. Taking it a step further, it is wrong to convince such nations at the international level that cyberspace should be used for the wrong purpose of changing policies against their own people or other countries.
- · They should also respond to aggressive cyber campaigns by other countries with economic and diplomatic measures designed to discourage cyber-aggression. State-rewarded, large-scale cyber-espionage must be deterred by frustrating or aggrandizing bad actors without accepting the price. The response should also include criminal charges and other legal action against those who steal intellectual property and other information, reducing visas for guilty parties and ceasing innocent cooperation. Encourage and allow the development of an effective and legitimate cyber-insurance business.
- · Protect the cyber-supply chain. As the components of smartphones, tablets and computers are almost identical and other gadgets are manufactured worldwide, it is important to evaluate supply chain operations, practices and security practices. Perhaps a voluntary organization could be formed that would make its assessment public and grade the technology company's supply chain operations.
- · An organization may charge more for its products if it receives a very high grade. A buyer will likely take the opportunity to purchase less secure and less expensive items if he is economically inclined. Consumers will be able to make informed decisions based on risk. Consider a regulated and specified cyber self-defense authority
- · An organization does not know what its right of self-defense against hackers really is. What do they do when an organization is attacked? Call the local police or the FBI? Can an organization fight back if attacked?
- · No one wants to have vigilance without any parameters or controls. To avoid this, the law should create basic and restrictive rules for self-defense only.
- · Expand the push for training, education and real awareness. These massive security awareness efforts should try to end both hype and ignorance. Let people know the truth about cyber threats and provide them with the tools they need to protect their businesses, homes and most importantly, themselves.
- · This effort should reach every community in the country at all levels. Regular training should also be conducted in every government organization and organization. Recruit and develop a strong cyber-workforce. Everything we do in the military, business and government can be affected by cyber security. Every nation needs to adjust certification and visa systems and promote science, technology, engineering and mathematics (STEM) so that the gifted and talented can use their skills to advance our security.
- · These efforts should update the security clearance process and tap into talent pools among the nation's hacker community, businesses, and military. Any legislation should enable this effort and encourage it in all possible ways.
- A word "Cyber Crime" came into Existence. In Short , all crimes committed or resorted by abusing electronic media, internet or otherwise , with the purpose of influence the functionality of computer system are come under "Cyber Crime".
List of Major cyber Crime are : (1) Hacking , (2) Virus Dissemination , (3) Salami Attack , (4) Business Rival's , (5) Ex-GirlsFriend.
Prevention from Cyber Crime:
1) Set a Secret code of your computer System.
2) Avoid Using Unnecessary things
3) Avoid Chatting with unknown person.
4) Don't not transaction on ATM Which is located in a lonely places.
5) Be careful while doing transaction electrically.
